Claude, In Marna Walle's 2.5 presentation she stated that 2.4 is the last level to support HFS. Here's the text accompanying the slide deck of her presentation.
z/OS 2.4 is the last release of the operating system to support the HFS (Hierarchical File System) data structure used by the z/OS UNIX environment. IBM has provided equivalent if not superior functionality with the z/OS File System (zFS). Customers should migrate from HFS to zFS using the utilities provided in the operating system to convert their entire file system hierarchy.

All, I remember reading somewhere that IBM is doing away with HFS support and for some reason I thought this was AFTER z/OS 2.5. However, a co-worker has found a small sentence that stated z/OS 2.5 will NOT support HFS file systems. We have converted most of our HFS to ZFS, so we are on the right path. I wanted to see if anyone knew the exact cutoff z/OS level for HFS support. Best Regards, Claude Richbourg Manager - Mainframe and iSeries Groups Florida Department of Financial Services 101 E.
